Anti-graffiti coating, useful to cover smooth, nonporous solid support, obtained under UV radiation by cross-linking of composition comprising resin; monomer and/or solvent; photoinitiator and optionally anti-UV agent

摘要

Anti-graffiti coating, to cover a smooth, nonporous solid support, obtained under UV radiation by cross-linking of a composition comprising at least a resin (urethane acrylates and urethane hydroxyl acrylates); at least a monomer and/or a solvent; at least a photoinitiator and optionally an anti-UV agent. Anti-graffiti coating, to cover a smooth, nonporous solid support, obtained under UV radiation by cross-linking of a composition comprising at least a resin (urethane acrylates and urethane hydroxyl acrylates); at least a monomer and/or a solvent; at least a photoinitiator and optionally an anti-UV agent (the selection of the components for the composition and the conditions for cross-linking are such that the coating presents a compact network of cross-links and acquires a classification G1 or G0 according to NFF 31-112 norm). An independent claim is also included for anti-graffiti treatment process on a smooth surface of a non-porous solid object, comprising application of a coating composition on a solid support; exposure of the solid support to UV radiation; application of a graffiti layer on the formed lacquer film; and elimination of the graffiti layer with the help of a cleansing agent having a solvent base.
